- Upload button no longer gets permanently stuck if startUpload()
throws after health check (try-catch with uploading=false reset)
- Wait for running health check instead of silently blocking upload
- Add abort signal check in VOE/Vidmoly upload generators
- Escape filenames with quotes/backslashes in multipart form headers
(all 4 uploaders: doodstream, voe, vidmoly, byse)
- Validate backup import structure before overwriting config
